Although many people deal with this problem including us, instead of analyzing the weak spots, we land on to a nearer place to the WiFi Router to gain the full signal strengths and downloading speed. However, we have a better option to know the accurate signal map of your home or office.

However, some people also carry a mental wifi signal map to avoid weak spots. Some move to the couch or an exact place to enjoy fast download and uploading speed. However, what if we tell you, you can avoid this kind of madness with the help of a WiFi Signal Scanner App for Windows? So to avoid the extra effort from you, we are here with the list of best WiFi Analyzer App to improve your Internet experience on WiFi.

Why Do I Need a WiFi Channel Scanner?

With improvements and innovations in technology, we are also getting dependant on it. WiFi is one of the most common and useful media to connect to the Internet and browse.

Now, even our home appliances require an Internet connection to get the latest updates remotely and get the latest and more advanced features.

So as the WiFi users are increasing, it becomes difficult to gain a constant decent downloading and uploading speeds. The reason this happens is that of the inherently limited WiFi frequency range which causes adjacent channels overlap and interfere with each other. Thus to avoid the interference and gain a decent speed, it is recommended to leave a couple of channels clear between used channels.

As most of the users are aware of this because they do not have a reliable WiFi channel scanner to use and get aware of the busiest and most reliable WiFi channels out there.

What Can a Windows WiFi Channel Scanner Do?

A WiFi Channel Scanner app will analyze and detect all the available WiFi networks around you. Moreover, it also provides detailed information about each one available channels. It also tells you the signal strength, how strong they are, and more details as the encryption techniques they have used.

Furthermore, some of the WiFi analyzer apps lets you create an accurate heat map of WiFi signal strength. These heat maps indicate areas of weak WiFi signal strengths, which helps you determine the best place for installing your WiFi router for constant speeds.
